The adhesive strength and initial viscosity of denture adhesives.

Abstract

Abstract
Objective. To examine the initial viscosity and adhesive strength of
modern denture adhesives in vitro. Materials and methods. Three
cream-type denture adhesives (Poligrip S, Corect Cream, Liodent Cream;
PGS, CRC, LDC) and three powder-type denture adhesives (Poligrip Powder,
New Faston, Zanfton; PGP, FSN, ZFN) were used in this study. The
initial viscosity was measured using a controlled-stress rheometer. The
adhesive strength was measured according to ISO-10873 recommended
procedures. All data were analyzed independently by one-way analysis of
variance combined with a Student-Newman-Keuls multiple comparison test
at a 5% level of significance.

Results. The initial viscosity of all the
cream-type denture adhesives was lower than the powder-type adhesives.
Before immersion in water, all the powder-type adhesives exhibited
higher adhesive strength than the cream-type adhesives. However, the
adhesive strength of cream-type denture adhesives increased
significantly and exceeded the powder-type denture adhesives after
immersion in water. For powder-type adhesives, the adhesive strength
significantly decreased after immersion in water for 60 min, while the
adhesive strength of the cream-type adhesives significantly decreased
after immersion in water for 180 min.
